Because gold is one of the heaviest elements
because of its denisty
It is initially done manually. In that you pick out the gold from the other rocks. After that there are various acids and chemicals that dissolve the gold and separate it from the other material
the gold will be alot more dense than the material you are panning, so by using subtle movements of the pan to separate these particles, the material is separated into soil stones and gold.
you weigh its density and compare it with the density of gold, if both densities are same, then the crown is made of pure gold. if the density of the crown is lower than the density of gold, then the crown is made of materials that are cheaper or have a density that is less than gold, meaning that it is not made of pure gold.
Gold is a kind of metallic ores . When mine gold, the flotation magnetic separation process is needed if you want to separate the gold out or if you want to improve the density of the gold. Hongj Mining Machinery is the expert of magnetic separation process, you can consult them.

If you are talking about buildcraft then you put the material you want as the pipe surrounding a glass. Ex. Gold-Glass-Gold.... Stone-Glass-Stone
ARCHIEMEDES was the first scientist who determine the density for the first time by observing the gold substances in water and said that the material have greater density remain below while the substance have low density flow on water..
The density of Fools Gold is 5.0
Density of gold: 19,282 g/cm3 Density of copper: 8,96 g/cm3
you weigh its density and compare it with the density of gold, if both densities are same, then the crown is made of pure gold. if the density of the crown is lower than the density of gold, then the crown is made of materials that are cheaper or have a density that is less than gold, meaning that it is not made of pure gold.
That depends on the density of the material in the cube. It would be different if, say, the cube were made of ice, iron, or gold.

you use an ore to separate gold from impuritties
If the gold is of the same purity the density will be the same.
